4SFP Module Slots (21–24):The four Small Form Factor Pluggable (SFP) transceiver slots allow you to install an SFP transceiver (purchased separately). These ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in any combination.

When an SFP module is installed in a slot and is active, the associated RJ-45 port (21 to 24) of the same number is disabled.

5SFP Module Status Indicator: The four SFP status LED indicators show the state of the SFP module ports (21 to 24; see #4).

■Green: An SFP fiber module is present.

■Off: No fiber module is present.

When an SFP module is present, the fiber port activity is indicated by the corresponding LED over the RJ-45 port (21 to 24):

■Green steady: Fiber link is present.

■Green flashing: Fiber link traffic is present.

■Off: Link is not present

6Fan Indicator: Shows the status of the internal fans.

Green steady: All fans are functioning properly.

Amber steady: The switch is too hot.

Amber flashing: One or more fans have failed

7System Indicator: Shows the overall status of the switch.

■Green steady: The switch is powered-up and operating normally.

■Green flashing: The switch is undergoing self test, initialization, or downloading.

■Amber steady: The switch has detected a hardware malfunction such as temperature, fan, or voltage.

■Off: No power. The switch is off.

8Console Port: Allows you to connect a terminal and perform out-of-band management. The default communications settings are 19200 bps, 8 data bits, no Parity, 1 stop bit.

9Reset Button: Use the reset button to restore the switch to its factory defaults. See “Restoring the Factory Default Settings” on page 29.

10AC Power Input: Accepts 100–240 Vac, 50/60 Hz input power. The switch automatically adjusts to the input voltage.

11Feet: These are self-adhesive pads. You do not need to install them if you are rack-mounting the switch.
